The life and work of one of the most influential psychological theorists of modern times. George Ivanovitch Gurdjieff is one of the most enigmatic figures of our time. He attracted legends as easily as disciples. But behind the Gurdjieff myth lies a solid corpus of thought, the importance of which is only now being generally recognized. At its heart was the idea of the war against sleep, the fact that man, in Colin Wilson s words, is like a grandfather clock driven by a watch-spring .This brilliant and much praised examination of a psychologist and teacher of genius has established itself as the most important and accessible account for the general reader of Gurdjieff s life and work. This edition has been revised and expanded, providing the definitive introduction to the philosophy of Gurdjieff."
